I need to know if the eight larger bolts holding the lower casting which includes the oil pan (I'd love to know the proper name of that part, block cradle?) are TTY?

The bolts that go into these holes:

Part numbers would also be amazing.

Those are the main caps, they hold the crankshaft in place. I am finding mixed info on these but the consensus is that they are TTY.
I read that they can be reused up to 5 times but on something that important I would just replace them for peace of mind.
YMMV
 












I think I may have stated this wrong. I don't have the block cradle off yet. Based on that excellent post it seems they are not TTY.

Engine block cradle (upper oil pan): (E/MWM)
...Inside bolts: Step 1: 11 lb-ft, Step 2: 24 lb-ft
...Perimeter bolts/nuts: 80 lb-in
...Threaded inserts: 27 lb-in
...Torx bolts: 71 lb-in
...Bell housing (lower rear) bolts: 32 lb-ft
 






Any other questions will be great
The forum is happy to help
 






This forum has been excessively helpful. Thanks guys, I'm giving back the best I can.
 






Yeah sorry about that
Now that i look harder at the pic i guess you aren’t talking about main cap bolts.
My bad
 






those are the main cap bolts that are circled they have a straight torque value so not torque to yield torque to yield has a torque value plus turn so many degrees
